Foliage growth is generally best around 6500K, though many plants need a period of warmer light, around 3000K, in order to produce flowers, and thus fruit.
In this regard, is 5000K or 6500K better for plants?
Both 5000k and 6500k are great for the vegetative phase, flowering phase, and fruiting phase. So, they are ideal for the general growth of your plants. The only difference between 5000k and 6500k is that 5000k is considered morning light. On the other hand, 6500k may be regarded as noon light.
Also, is 6500K too bright?
6500K is in the lower end of the blue spectrum and is considered by many to be a good “work light” temperature. A “warm white” lamp bulb is generally 2500 or 3000.
Will 6000K LED grow plants?
The 50W , 6000K LED lights provides full spectrum light that’s optimal for plant growth.
Full spectrum lights offer a colour temperature of 6500K and a CRI of 96%, and so, in comparison to daylight bulbs, full spectrum bulbs can provide a brighter, whiter light with better colour rendering.

|4500K, preferable closer to the range of 6000-6500K.
Often referred to a purple, or blurple, LEDs, the manufacturers of these lights refer to them as “full spectrum”. But they are not. Even if they have diodes in many other colors, they are not really full spectrum.
Light Brightness and Lumens
Vegetable seedlings and other “full sun” plants require about 2000 to 3000 lumens (at minimum) per square foot of growing space. So, if you’re growing just a single standard tray of seedlings, using a grow light that emits 3000 lumens is sufficient.
Plants do best with a light that has a lot of red and blue and smaller amounts of green and yellow. White light is not important for plants – having the right amount of each wavelength is important.
What’s the difference between LED lights and LED grow lights? Standard LED lights only provide illumination while LED grow lights have a wider spectrum of both blue and red light that promote vegetative growth and flowering, respectively.
Both 5000K and 6500K white light is great for growing plants, but not as great for flowering them. It will still work fine, but a warmer color temperature would work much better.
